Definitions

  • the invention relates to a suction jet pump with improved suction.
  • Suction jet pumps are used, for example, in fuel tanks Motor vehicles used to remove fuel from an area of the fuel tank to promote another area.
  • Suction jet pumps are nowadays used in fuel tanks in motor vehicles used and are therefore known. Your job is to fuel out distant and deeper areas of the fuel tank to the delivery unit or to promote in a baffle.
  • the suction jet pump is there essentially of a propulsion jet pipe, a suction opening and a Mixing tube.
  • the quantity fed through the jet nozzle of the suction jet pump liquid emerges under pressure from the boundary of the jet tube Jet nozzle and then into the mixing tube.
  • the suction opening for the liquid to be pumped is between the jet nozzle and the Mixing tube arranged.
  • the driving steel entering the mixing tube produces before the mixing tube a negative pressure, so that the liquid to be pumped over the Suction opening is sucked into the mixing tube.
  • the efficiency of one The suction jet pump is dependent on many factors. So influence, for example the length of the mixing tube and other geometric factors Efficiency.
  • the general disadvantage of suction jet pumps is their relatively low efficiency of approx. 20 to 30%.
  • the invention is therefore based on the object of having a suction jet pump to create improved suction that is simple in construction and not a large one Space required.
  • suction jet pump improved suction, which on the rapid liquid closure in the diffuser is returned. Furthermore the suction jet pump has a very simple structure and is stressed little space.
  • the nozzle opening is Driving jet nozzle designed such that it generates a flat jet.
  • the diffuser in this case has an elliptical inlet cone adapted to the flat jet.
  • a nozzle opening which has a transverse notch, is particularly advantageous owns.
  • the driving jet is expanded in a fan shape.
  • a web is arranged in the nozzle opening, which contains the driving jet divides and thus generates the flat jet.
  • it is also a nozzle opening conceivable, which has a plurality of openings arranged in a line, so that the Form individual beams into a flat beam.
  • FIG. 1 shows a section through a suction jet pump according to the invention
  • Figure 2 is a top view of the mixing tube with an elliptical diffuser.
  • the suction jet pump shown in Figure 1 consists of an upper part 1 and a lower part 2.
  • the upper part 1 has a connecting piece 3 for one Driving jet line shown through which the propellant of the suction jet pump is fed.
  • the connection piece 3 is surrounded by an outer housing part 4.
  • the jet nozzle 5 closes their nozzle opening 6.
  • a transverse notch 7 causes the fan-shaped Widening the jet.
  • the lower part 2 of the suction jet pump is formed by the mixing tube 8 and the diffuser 9, the diffuser 9 in an interior Housing part 10 merges.
  • This inner housing part 10 is in the outer Housing part 4 inserted and locked by means of a sealing ring 11 the upper part 1 tightly connected.
  • a nozzle 12 forming the suction opening is arranged above the liquid sucked into the suction jet pump and via the mixing tube into a likewise line, not shown, is promoted.
  • two resilient locking hooks 13 formed on the upper part 1 can be deflected by operating the spring arms 14.
  • Figure 2 shows the lower part 2 with the inner housing part 10 and the elliptical trained diffuser 9, which merges into the cylindrical mixing tube 8.
  • the nozzle 12 is arranged at an angle of 90 ° to the inner housing part 10.
